Abstract: A measuring rod for measuring a fill level of a lubricant in a reservoir of an internal combustion engine includes a rod element, at one end of which is arranged a measuring tongue which can be submerged into the lubricant and by which the fill level can be measured and can be detected visually. At least one sealing element is arranged on the measuring tongue, by way of which the measuring rod can be sealed in relation to a guide tube for guiding the measuring rod.

Abstract: A shaft bearing point has a radial shaft bearing in which a drive shaft is rotatably supported relative to a machine housing. The radial shaft bearing is arranged directly or indirectly in a machine housing wall separating a lubricant space from a lubricant-free space. The radial shaft bearing has a lubricant side facing the lubricant space, and a seal side facing away from the lubricant space, in the axial direction, and a radial shaft seal is provided which is arranged at an axial distance to the seal side such that a lubricant chamber is produced between the seal side and the radial shaft seal ring in the axial direction. The lubricant chamber is equipped with a chamber separating wall. The chamber separating wall separates the lubricant chamber into a storage chamber, which is arranged between the seal side and the chamber separating wall, and a seal chamber, which is arranged between the chamber separating wall and the radial shaft seal ring.

Abstract: A two-part oil pan for an internal combustion engine has a box portion and a pan portion. The pan portion forms a floor of the oil pan and the box portion forms a pan wall of the oil pan. On a peripheral edge having a peripheral first sealing surface on the pan portion and a peripheral second sealing surface on the box portion, the box portion and the pan portion are interconnected in a sealed manner by means of first connection means. The pan portion and the box portion additionally are interconnected by at least one second connection means which is arranged within the edge and additionally at a distance from said edge.

Abstract: An oil measurement apparatus for an oil-lubricated internal combustion engine has an oil dipstick and a guide for guiding the oil dipstick in an oil pan of the internal combustion engine. A fill level of motor oil in the oil pan can be recorded by the oil measurement apparatus. The oil dipstick has an operating element in a first end region for inserting and removing the oil dipstick in the guide and, in a second end region, has a measurement region for recording the fill level. The fill level can be recorded by the oil dipstick in a first state of the oil measurement apparatus and, in a second state of the oil measurement apparatus, the measurement region is completely drawn into the guide. The oil dipstick has a dipstick stop element between the operating element and the measurement region, and has a dipstick cover, which is movable between the measurement region and the dipstick stop element and is designed to at least temporarily cover the measurement region.

Abstract: An assembly tool is provided for connecting a fastening element to at least one component. The assembly tool has a marking device, which is designed to apply a first type of marking to a fastening element when a first connecting step is finished, and to apply a second type of marking to a fastening element when a second connecting step is finished.

Abstract: An engine block with an oil path switching arrangement is proposed. The engine block includes an oil sump, an oil pump, a clean oil riser and a switching valve. The switching valve has in each case connections for the oil sump, the oil pump and the clean oil riser. The switching valve is switchable to open and close the connections, including a first position in which a connection between the clean oil riser and the oil sump is established, thereby avoiding discharge of oil in the clean oil riser through an oil filter receptacle during an oil change.
